I have a 2014 CX-5 GT. The car is key-less entry and push-button start. The key fob has a detachable key that looks like any other auto key, yet the car has no key entry point to place the key. So why, do I have this key? I checked the Manual and it only references a auxiliary key and how to detach it from the fob. Any one have an answer to why there is a key at all if there is no place to insert it?
